One of the few natural springs left in Texas and one of just a handful on public property, Big Spring is quickly becoming a focal point of intense study in the Great Trinity Forest. So much is yet to be learned about this natural spring that for every question and answer, another ten questions are spawned. The random guessing and hypothetical discussion of such a place has lately turned into a search for hard facts, scientific discovery and a determined goal for perpetual preservation.

Looking down into Big Spring

The unknowns of the place still vastly outweigh the knowns. How old is the spring, how old is the water, who lived here, who visited here, what's under the ground, how was the spring formed. Slowly some of those questions are being answered. It will likely take years to fully understand the place.

The search for answers is a fun project. With an average flow of 23 gallons per minute year round and water pure enough to drink, the Spring is a great outdoor classroom for not just children but adults too. Classified as a Magnitude Five natural spring, delivering over 8 million gallons of clean water annually to the Trinity River watershed it might be one of the cleanest if not the cleanest source of water on the whole of the 710 miles of Trinity River. For certain the cleanest water in the watershed in Dallas County. Bar none. If there is cleaner water, I cannot find it.

Radiocarbon Dating Big Spring's Water To the 14th Century
In addition to monthly water monitoring, one of the most unique tests conducted recently was a radiocarbon dating test of the water at Big Spring. The $600 cost for the test was paid for by fourteen citizens interested in the preservation cause. Conducted in late August 2013, the water test was sent to Beta Analytic in Florida for analysis.

The results took the balance of a month to get back and show the water being dated to 1360 AD. When dealing with variables like water, many things factor into the age of the sample taken. The soils and rock it flows through, surface water permeating into the aquifer, testing methods. All have an effect on the water's age. At the bare minimum the results show that the water and aquifer that supply Big Spring are not modern. They are very old and could very well be much older than 1360. So many things factor into how to age the spring that it would take many more tests at different parts of the aquifer to gain a comprehensive insight into the age and size of the aquifer that feeds the spring.

The water test was led by archeologist Tim Dalbey. He had floated the idea of the test for over a year and with enough backing and monetary support was able to get the water sample required. Tim does all kinds of interesting things around town. One of the more recent was a mid 19th century cistern discovered by work crews doing renovations of Dealey Plaza in preparation for the 50th anniversary of the JFK assassination. The cistern sits mere feet from the School Book Depository in Downtown Dallas. Byron Harris from Channel 8's report is below, featuring Tim, the cistern and the assassination:

Current Water Testing Efforts
Tim also ponied up for a water test at Big Spring over a year ago which included a chemical analysis of the water. Those results can be found here June 2012 Water Quality Test At Big Spring
The importance of tests and monitoring is designed to establish a baseline for the future. Starting recently from square one with much of the data collection the avalanche of data regarding the spring and surrounding area now exceeds 5,000 pages of documents and is growing all the time.

The Texas Stream Team, formerly Texas Watch, is based at Texas State University and is affiliated with the university's River Systems Institute. The team is a partnership of agencies and trained volunteers working together to monitor water quality and educate residents about the natural resources in the state. Established in 1991, the team is administered through a cooperative partnership with Texas State, the Texas Commission on Environmental Quality (TCEQ) and the Environmental Protection Agency (EPA). The more than 2,000 volunteers are trained to collect water samples according to a water quality plan approved by TCEQ and EPA. The monitors make field observations and analyze the samples for dissolved oxygen, pH, specific conductance, Secchi depth transparency, temperature, and E. coli to assess the quality of aquatic life and contact recreation conditions of the water.

Big Spring has not one but now two data testing sites in conjunction with the Texas Stream Team. Led by Richard Grayson, the DFW coordinator, the two sites labeled:

Big Spring sits in southeast Dallas 32°43'49.06"N 96°43'15.49"W , the neighborhood of Pleasant Grove and the subsection of an area called Pemberton Hill. At roughly 405 feet above sea level, the spring sits in what geologists call the Trinity Terrace.

The Trinity Terrace is a series of orangeish and brown-yellow Pleistocene gravel deposits from a long ago time. The Pleistocene is the geological epoch which lasted from about 2.5 million to 11,000 years ago, spanning the world's recent period of repeated glaciations. During that time, a vast ice age here in North America, ice sheets and glaciers extended as far south as Kansas. Coupled with much wetter weather than today, the Trinity River was vastly larger, carrying large loads of sediment across a valley that extended from Fair Park clear across to the Dallas Zoo. Big and mighty river, large flood events to boot.

The large flood events deposited gravels over the underlying Austin Chalk. The Austin Chalk was deposited roughly 80-90 million years ago during the cretaceous when Dallas was covered in a large sea. In a rare few places you can still see the Trinity Terrace gravel overlying the Austin Chalk.

McCommas Bluff Preserve on the Trinity River

One such place is historic McCommas Bluff, just downstream from the Trinity River Audubon Center. Here one can easily pick out in the northern section of the bluffs, the Trinity Terrace deposits stacked atop the older Austin Chalk.

Much of the gravel and sand here is loose, one can pick some up barehanded with no effort. In some areas where water has infiltrated over time, the matrix has cemented together. The calcium carbonate solution in the water binds the gravel and sand together forming a hard rock structure.

If one looks carefully at the photo above you can see the voids created over time by water slowly moving through the rock at McCommas Bluff.

At one particular place along McCommas Bluff a natural seep exists where water exploits a void/flaw/crack/crevice in the limestone. Here the groundwater has created a deep void with crystalline calcium carbonate inside of it. Above is the water bearing Trinity Terrace gravel.

The seeps at McCommas Bluff are fragile. Easily impacted by surface activity in the recharge zone beyond. Some seeps have stopped flowing here, others a mere trickle compared to a few years ago. The cause of the degradation was a construction project by Dallas Water Utilities that compacted and ruined much of the land here. Despite assurances that the area was going to be reseeded with new native grass and wildflowers, it never came to pass.

Getting Back To Big Spring

The same geologic structures seen at McCommas Bluff can be seen with a discriminating eye at Big Spring. Looking closely through the vegetation and soil, one can pick out the gravel and limestone boundary inside the spring. Above, Dr Tim Dalbey stands at one source of Big Spring to the right of the photo. To the left and in the background one can pick out the clearly defined limestone vertical face.

More study is required to find out what makes the spring work so well. With such a volume of water one can only wonder what kind of geology focuses so much H2O in one spot.

Loss Of Nearly All Natural Historic Springs

There was a time when Dallas was dotted with springs. Well known in name only, Cedar
Springs and Kidd Springs are both great examples of what were once
large, functional and important springs in Dallas. There are many more
like Keller Springs, Balch Springs and Grapevine Springs that either no
longer flow or have been so heavily altered over time that they no
longer serve as a touch stone to the past.

There is one
place though, one natural spring of importance still out there, that
has sat in relative isolation and free from the hands of man. That place
is called Big Spring, in the Great Trinity Forest, Dallas, Texas.

Cedar Springs

Across the street from the Whole Foods grocery store in Highland Park
stands a modest inscribed stone laid in 1936 to mark the site of Cedar
Springs. People know the name. Hundreds of thousands of people drive the
road every day bearing the same name. Few have ever seen the actual Cedar Springs or what remains of them not encased in concrete.

Cedar Springs townsite in Dallas Texas, south of Lemmon Avenue and east of the Dallas North Tollroad

If you could thumb back through that history book and find a year
that exemplified a time when the land was fresh in Dallas it would be
1843. Dallas in that year was a vast unpeopled wilderness of plains,
known for lush riparian bottoms and a bounty of wild game. The city as
we know it today was no more than a dugout scrape of a hovel occupied by
one man, John Neely Bryan. Dotting the distant landscape of what was
then Nacogdoches County in the Republic of Texas were a scant few
homesteads of pioneer families who decided to call what is now Dallas,
home. Dallas was not even a going concern at the time. It was Cedar Springs.

Before there was even a Dallas, Cedar Springs served as a small military bivouac for the Republic of Texas. Here Texan military units were reported to camp, exploring and surveying an untamed land that later became DFW. Preston Road was laid out from here. A connection from Holland Coffee's Trading Post on the Red River at Preston's Bend with points south towards Austin. Here is where it all happened.

For a time, a serious effort was underway to determine what town should hold the county seat, Dallas or Cedar Springs. The springs were superior to what was offered in Dallas near what is now the Old Red Courthouse. Better land, better water, better living conditions all around. Cedar Springs in it's heyday boasted a distillery, grist mill, sawmill and a variety of businesses that used the spring for light manufacturing before the Civil War. Those times are long gone, after an election that made Dallas the county seat.

Cedar Springs as it exists today

At the back end of a city park sits the remains of Cedar Springs. Barely a trickle from it's source, most likely ruined long ago by a construction project. Bisected by a chain link fence and full of trash, it's water begins a slow trip under the Dallas North Tollroad.

Under the tollroad in some mix of concrete culverts the water from Cedar Springs mixes with drainages from western portions of Highland Park to form Cedar Springs Branch. Here the flow is a little stronger, just 100 yards distant from the head of Cedar Springs itself.

The west side of the tollroad is where the bulk of the residents lived in what was once Cedar Springs. The waterway is channelized now in a culvert as it passes through a series of gated condo communities and apartment complexes.

Behind one such set of high gates and fences sits a Texas Historical Marker for Cedar Springs. Hard to read from the street(click on the photo to read the inscription). Nothing remains to take stock of today. Long ago gone. Only a street name remains to note the place ever existed.

Kidd Springs

Kidd Springs Park in Oak Cliff

When Kidd Springs was a going concern, the spring fed lake here was one of the finest swimming holes in the United States. Originally the spring was used by Oak Cliff pioneers in the 1840s-1850s as a water source. When the namesake for the spring Colonel James Kidd purchased the 200 acres of property around the site, he improved upon it. The improvements included turning a natural ravine into a lake via a dam on the northeast and drilling down some distance to improve the flow. The result was a manmade artisanal source up near present day Fouraker Street just north of Davis that ran down to the lake via pipe and then bubbled up into the lake.

Kidd Springs at the turn of the last century is where the elite in Dallas spent their summer weekends. A cross between a waterpark and amusement park, Kidd Springs was the place to be seen and put Oak Cliff on the map. Oak Cliff as a community always boasted their clean water as compared to Dallas across the river, Kidd Springs was evidence of that.

Like Cedar Springs, the wheels came off Kidd Springs long ago. Maybe it was the polio scare or the 50's drought that did the place in. Over time the place just became little more than a memory in the heads of the old timers, people who recalled the elite country club atmosphere of a place long since gone.

Improvements to Kidd Springs Park where the lake now sits incrementally crept away from the lake itself and the park now is as cookie cutter as any other in the city. Concrete sidewalks that replaced the old asian motif decor, the rock work replaced by more functional but bland access for ADA compliance.

Big Spring
Seventeen decades, a whole 170 years of documented Texas history lie here. In a chronological history book of Dallas history, the intertwined lore of this spot would be written on page one.

The evening sun setting behind Big Spring

Around the time Cedar Springs was founded, a year or two after John Neely Bryan started calling his dugout hole near what as now the Old Red Courthouse, a family called the Beemans settled in North Texas on lower White Rock Creek.

Veterans of the Republic of Texas Army and Indian campaigns, the Beemans by the early 1840s had already made their mark on the infant Republic's history. They settled on White Rock Creek on land claims given to them by the Republic of Texas for military service and land purchased via Toby Script. One parcel of land was known as the "Big Spring Survey", claimed in 1842 by John Beeman in what was then the Peter's Colony Survey. John Beeman and his family lived on the west bank of White Rock Creek just down the hill from the present day Beeman Family Cemetery.

Big Spring as it looked on the evening of August 13, 2013, 170 years to the date that President Sam Houston camped here

John Beeman called this piece of land "Big Spring" after the cold and clear water that flows straight off the bedrock via a natural spring. Used for countless centuries by Native Americans, this site had been a magnet for humans seeking water and refuge. Even present day the water still flows at a near consistent 60 degrees. Who knows what kind of people once drank from the water here. What language they spoke. What they ate for dinner.

Sam Houston and his Treaty Party visit Dallas and a high probability that they camped one night at Big Spring

Sam Houston

Sam Houston had lived with the Cherokee people for years as a young man, had a fondness for the tribes and wanted them treated fairly as their lands were taken over by civilization despite their depredations against the settlers in Texas. For months Houston sent messages to his Indian friends proclaiming he would hold a Grand Council of the Tribes at Fort Bird(presently in the North Arlington area) during the full moon of August 1843. Similar to what we might consider a general assembly meeting of the United Nations. Houston sent Indian Commissioner Joseph C. Eldridge out months in advance of the date to bring the Comanches and others to the treaty council.

It was in August 1843 when Sam Houston and an expedition of about 30 men departed Crockett in East Texas, and began their trek to the Three Forks of the Trinity(now known as Dallas and Tarrant County) to negotiate with the chiefs of the Indian tribes. Their route was well documented traveling roughly on the same route into Dallas that US Highway 175 takes today. This route was an ancient Pre-Columbian trail used by Indians for many centuries as an important trade route between the Piney Woods of East Texas, the Plains and Indians living north of the Red River. Scyene and Preston Roads share similar distinctions in Dallas as ancient Indian trails that later became major roads.

One of the men in his group was an Englishman by the name of Edward Parkinson. He kept a detailed account of the trip in his diary. It's believed he came along just for the adventure of seeing real live Indians on the plains. At the time the Beeman family was living in a blockhouse near present day Dolphin Road and Military Parkway. The account below mentions that they did not see the Beeman family until the next morning, August 14th 1843. His diary entries from August 13th and 14th or there abouts follow.....

"We encamped that night at White Rock Springs, so called from the calcareous nature of the rocks abundant here about one mile from the White Rock Fork of the Trinity. In the morning some settlers from the infant colony opened about the Forks of the Trinity River visited us, accompanied by some travelers examining the country, they brought us no news of the expected Indians and were on foot, stating that some little time previous the wild Indians had stolen all the horses but one or two belonging to the settlement. We then saddled up and proceeded to the fork at White Rock Creek which we found very difficult from the rain which had fallen making the bank on the other side one slide of about thirty feet, from top to bottom. We were obliged to dismount and drive the animals over, some of them describing curious mathematical figures, from their inexperience in the science of sliding. However, all got over safe, and on reaching the prairie on the other side arrived at one of the colonist’s cabins{that of John Beeman} where we were regaled with an acceptable and plentiful supply of buttermilk. My horse(a mustang) having become almost knocked up, I determined upon resting here, and was hospitably entertained until the following day, the company in the meantime moving on to Cedar Springs, where they rested a day or two previous to marching on to Bird’s Fort on the West Fork of the Trinity the appointed Treaty Ground, great anxiety prevailing respecting the Indians but no news of them."--Edward Parkinson 1843

Sam Houston

When Houston arrived at Ft. Bird, several tribes had shown up but did
not want to go near the garrisoned fort fearing a trap. Houston moved
the negotiations and camps six miles north to Grapevine Springs. He
felt the Springs offered better water, more shade in the summer heat and
less mosquitoes. However the group camped there for more than a month
while awaiting the Comanches, and was described by Parkinson as: "there
were some fine though rather monotonous days, only relieved by finding a
bee tree or killing our beeves." Finally Houston realized the Comanches
weren't coming and decided to have a council with those in attendance.
Known as a flamboyant dresser, Houston's attire for the occasion was
noteworthy. "Donned in a purple velvet suit, with a huge Bowie knife
thrust in his belt, and a folded Indian blanket draped over one shoulder
to proclaim his brotherhood with the red men, Houston eloquently
promised the chiefs that a favorable treaty line would be drawn beyond
which the Indians could live unmolested by white men." At this time,
along with the negotiations with the Indians, Houston was still
President of the Republic and having to deal with the Mexican situation
and annexation of Texas. Before the actual treaty was signed, he had to
go back to Washington on the Brazos to deal with these issues
personally. To deal with the Comanches when, and if, they arrived he
assigned Gen. Edward H. Tarrant and Gen. George Whitfield Terrell.

Treaty of Bird's Fort

The
treaty was signed in the last three days of September 1843. The Treaty
at Birds Fort was a rare instrument: it was actually ratified by the
Republic of Texas Senate. Throughout both his administrations, Sam
Houston worked to negotiate with the Texas tribes, not only because of
his natural inclination but also because the new Republic simply could
not afford to be at war both with the Indians and the Mexicans. His
policy had already been put into practice when he and John Forbes
negotiated a treaty with the Cherokee on February 3, 1836. President
Mirabeau B. Lamar, on the other hand, was convinced that the tribes were
conspiring with the Mexicans, and he also believed that the tribes
constituted a foreign nation in competition with the Republic. He
actively supported a policy of extermination and expulsion, a policy
which removed the Cherokee altogether and which helped plunge the new
nation into considerable debt.

Native Americans

Springs in Texas have been a magnet for human activity for many dozens of centuries. Find an undisturbed spring site almost anywhere in the Lone Star State and one will readily find evidence of human occupation that goes back thousands of years. The old watering holes of the first Americans later became well worn routes of travel that were used by the first European expeditions to Texas. Those old game trails and hunting routes eventually morphed into wagon roads, some became modern day highways we know today.

A wide swath of an archeological site once covered the terrace upon which Big Spring sits. Over the last hundred years, through utility right of ways, easements and some gravel mining, the site, officially called 41DL72 slowly diminished in size. Remnants of the site still exist undisturbed. The effort to save the remaining undisturbed area for the future is a tough sell.

Measuring DL72 in the electric ROW

For an area that looks so quiet, so untouched, the complexity of issues facing the place can best be described in the map above. What are 6 maps laid over one another show all the competing projects and eyes on design for the place. Some ideas, like the fencing of the spring are now just a distant memory. Others are still a concern as bulldozers begin work on the Texas Horse Park.

The work to map some of the areas has consumed many an early Saturday morning this summer. Measuring, driving stakes, measuring again, taking copious field notes and photos. All to preserve a place that links some ancient people to us. I don't even know who they are. No one does. If the bulldozers don't wreck it maybe one day we will find out.

Protecting the spring and the surrounding area is vitally important to the health and long term sustainability of Big Spring and the Native American site around it. "Protecting" and "protection" of a place can mean many things to many people. How one comes to consensus on what is best to protect one of the last natural springs in Texas, how we all figure that out is a tough one. Lots of big, gigantic promises being made. Hope it's not all talk.

The large field above Big Spring which serves as a bio-buffer for the spring

According to the City of Dallas, hired consultants for a time floated the idea of equipment buildings, two 1,000 gallon fuel tanks and a compost heap that would have commanded most of the land in the field here. See inset left. Those plans according to the City of Dallas were only ideas and never a serious consideration.

Talks with the city thus far in reaching preservation and conservation status have been productive and are seeing much progress. A large buffer is the right solution to the perpetual preservation of the Big Spring site, the preservation of the Native American site and leaving the woods surrounding the Spring free of anything but foot traffic. It should be a place that is open and enjoyed by all who want to visit. With discussion for a detailed and comprehensive management plan, conservation and preservation it's thought that the sights and sounds seen today will look the same 500 years from now. There is an abundant and rich reward for leaving places like this alone.

Thursday, September 19, 2013

The coda of brief sketches on the Trinity usually involves a note about sustainability or conservation for the future. More often than not pernicious future plans by some well meaning folk accidentally threaten to bump whatever is already inhabiting the woods down here out of the picture.

It's so very hard to express the rarity of wildlife movement through the Great Trinity Forest in Dallas or tell in words or pictures what is really there. What makes it a special place like no other in North Texas is hard to show. So many birds down there look alike, so many other animals are of a secretive nature where one only sees faint footprints rather than the creature itself. Every once in awhile, an animal moves through, that strikes pause in everyone who sees it. The Roseate Spoonbill is one such bird that fits all the criteria.

There are only two large pink hued birds in the United States, the Pink Flamingo and the Roseate Spoonbill. Natives of the sub-tropics, tropics and coastal areas, seeing either of the two species in the United States makes for a real treat.

As the crow flies, the Gulf of Mexico sits three hundred miles from Dallas. The buffered distance keeps all but a very few saltwater loving birds from ever reaching North Texas. It's during the waning days of August and September that the birds of the Gulf and of points further south move into North Texas.

Often during this period the seabreeze fronts that march north during the day from the Gulf will reach the southern fringes of Dallas County creating strong tropical downpours not common to the area the majority of the year. The area known as the Great Trinity Forest, in the Trinity River bottoms south of Downtown saw a number of the storms over the summer. The aggregate rain gave the area an extra 5-6 inches of measured rain over the course of the summer, keeping small bodies of water like Little Lemmon Lake at near normal levels.

Tlāuhquechōl -- The Divine Spoonbill

Montezuma's head dress adorned with red Roseate Spoonbill feathers

The Aztecs of what is now Central Mexico placed a high religious status on the mythical powers of the Roseate Spoonbill's colorful feathers. Tlāuhquechōl is the Nahuatl language word for Divine Spoonbill i.e. Roseate Spoonbill. The traditions of the Aztec tightly wove the lore of many birds into their codec books and ceremonial wear.

Above is a depiction of Tezcatlipoca one of the Aztec deities most known as ruler of the night sky, the night winds, hurricanes and the earth. The color of the night, dark and storm of the depictions are offset by the color of the Roseate Spoonbill head, body and feathers.

Aztec emperor Montezuma wore Roseate Spoonbill plumage in his royal head dress. Seen above left, his ornate feathered headpiece is adorned throughout by the feathers of the Roseate Spoonbill.

Roseate Spoonbills (Platalea ajaja) , which share the same pink plumage and long twiggy legs as
flamingos, are actually members of the ibis family. Generally smaller
than flamingos, Roseate Spoonbills grow to a height of 32 inches with a
wingspan of 50 inches, have shorter necks, and longer, spoon-shaped
bills.

Breeding populations are found along the south Florida coast from the Florida
Keys north to St Joseph Bay, with some populations in northeastern
Florida and along the coasts of Texas and Louisiana. The worldwide
population is only 175,000 with 30,000 living in North America.
Whittling down that number further, many of those 30,000 live in
Florida, the Caribbean or along the Gulf Coast. It is estimated that
there are 5,500 breeding pairs in the USA.

Juvenile Spoonbill in flight over the Great Trinity Forest, Joppa Preserve, September 2013, note the white feathered head

Here in the Great Trinity Forest it is interesting to see juvenile Roseate Spoonbills mixed in with adults. You have to look closely to see them. The juveniles have white feathered heads where the adults have a bald green toned head. If you look closely at the photos here you should be able to pick them out of the crowd.

Spoonbills consume a varied diet of small fish, amphibians, aquatic invertebrates, and some plant material. They feed in the early morning and evening hours by wading through shallow water with their bills partially submerged. As a Roseate Spoonbill walks it swings its head back and forth in a sideways motion. When the bird feels a prey item it snaps its bill closed, pulls the prey out of the water, and swallows it

A rare sight in North Texas, Roseate Spoonbills can be seen infrequently
in the shallow drying ponds and swamps in the Great Trinity Forest.
Spoonbills are traditionally coastal birds and are a regular site along
the Texas Gulf Coast. Rare to see them hundreds of miles inland in not
only a prairie but also a densely populated urban environment.

The Roseate Spoonbill is typically a far southern bird of the Americas,
breeding in Southern Mexico and Central America. In the United States it
is found only along the far southern Gulf Coast to any degree. During
late summer and early fall the birds move inland searching for food and
habitat along marshes and shallow ponds.

The average lifespan of a Roseate Spoonbill in the wild is estimated at
28 years. During the course of its life a Spoonbill might have twenty
solid breeding seasons and successfully raise young many of those years. It's rather remarkable to let your mind wander that these birds come back year after year. I have been seeing them every year like clockwork since 2007 here. Despite the small numbered flock of Spoonbills that visit, I cannot pick out individuals from one year to the next. I know they must surely be the same birds over the years. How many hundreds or most likely since they travel with Wood Storks, thousands of miles makes for an exceptional migration.

Protecting Roseate Spoonbills
During the early 1900s, Roseate Spoonbill populations from Texas through
Florida were nearly extincted due to hunters and trappers who killed
the birds and collected their feathers for the ladies hat industry. By
the 1940s it was reported that the breeding population of spoonbills
along the Gulf Coast may have numbered as few as 30 nesting pairs.
Protection efforts after that time aided the birds in reestablishing
nesting colonies, and by the late 1970s, the US population was estimated
to be approximately 1,400 breeding pairs.

The shallow feeding areas of the Roseate Spoonbill is paramount to the species survival. Little Lemmon Lake and other pocket ponds and abandoned gravel quarries that dot this part of town serve as critical habitat for these wading birds.

As mentioned earlier, the Roseate Spoonbill is typically a far southern bird of the Americas, breeding in Southern Mexico and Central America. In the United States it is found only along the far southern Gulf Coast to any degree. During late summer and early fall the birds move inland searching for food and habitat along marshes and shallow ponds. Called "dispersal" the adults with young in tow forage in ever broadening ranges late in the summer searching for food.

The Great Trinity Forest serves as a refuge for the Spoonbill, Wood Stork and other wading birds of the tropics during summer. So lost and so forgotten is the natural course of the Trinity River through South Dallas that I would imagine no human rightly knows what is down there as a whole. The birds do.

Wood Storks and Roseate Spoonbills take flight at Little Lemmon Lake, August 2013

Today, habitat loss and degradation of forging and nesting habitats
are the primary conservation concerns for roseate spoonbills in the
United States. In addition, creating new habitat is an expensive and time consuming process. Preserving what is already here, giving the Roseate Spoonbill and Wood Storks some elbow room is cheap. It's free. Do nothing and reap the rewards. The birds are already here and love the place.

The Future Will Be Here Sooner Than You Think

City of Dallas Assistant Park and Recreation Director Michael Hellmann discussing his plan for the Audubon to Arboretum Trail

I believe that the photo above might well have been taken as far from any paved road as one can get inside Loop 12. There among the 8' Giant Ragweed of the Great Trinity Forest near the mouth of White Rock Creek a lot of discussion took place, good constructive talk, about what the future has in store for this rare remaining wildscape inside the city limits. Stay tuned for how that pans out. Better yet, get involved yourself.

I think it's rather remarkable that the City of Dallas has taken an ear and a close look at many of the concerns down here and that is commendable. Rare that one of the largest cities in the United States took vast chunks of time out of their schedule to look into the topics of preservation and conservation in a place so few know about. That includes heads and managers from many different city departments.

Sean Fitzgerald listening to discussion between the Corps of Engineers scientists and Sarah Standifer with the City of Dallas

So much of this is still very much Square One. How do you take something so wild and natural, preserve, protect and conserve it. Part of the answer might come from Dr Gary Dick and Lynde Dodd both of the US Army Corps of Engineers Lewisville Aquatic Ecosystem Research Facility, LAERF.

They have been managing the Trinity River Wetland Cells since they were created out of the old Sleepy Hollow Country Club. Couple of articles about the two scientists:

Eating pears off of a tree in Wallace Jenkins old pear orchard, future Horse Park

Many of these places are wild, purely because no human ever goes there. Over many years, wildlife fills the void. For instance, Pond B known for years as Jenkins Lake, sits directly across the Trinity River from Wetland Cell G. A two minute flight for any bird. For a human, it's 20 minute drive down three roads and across Loop 12 and back again.

Interesting to listen to the Corps folks walk and talk about possible ideas for how to manage invasive species, wildlife and plants down here in the future.

Sweat equity by the gallon is getting expended to make this something everyone can be proud of. I think that slowly but surely stars are aligning and middle ground found in this process that will preserve the special areas down here in the future. The word "perpetuity" was said at city hall more than once.
